Cumulative incidence of hematopoietic recovery. Cumulative incidence of neutrophil (A,C) and platelet (B,D) recovery, as defined by CIBMTR criteria. Cumulative incidence estimated by the Kalbfleisch and Prentice method with univariate comparisons across categories according to Gray’s test and stratified by entire cohort (A-B) or by pre-LD platelet count (C-D, grouped by quartiles). Shaded areas represent 95% CIs.
